Zinc casting is a precision casting method that uses high pressure to force the metal to be hydraulically poured into a complex metal mold. It is a precision casting method
Plastic injection mold mold design needs to shrink water according to the shrinkage rate of different materials, and the Casting die basically has no shrinkage, the size of the mold cavity is large, and the product size is large; the biggest difference between the two molds is the glue. The gate of the die-casting mold is different from the injection mold, and the high pressure of the split-flow decomposition flow is required. The material path and feed port of the die-casting mold are generally much larger than the plastic, so it is difficult to modify, especially the aluminum alloy die-casting mold, which uses a piston-type injection to fill the mold cavity, the handle is large, and the plastic mold is injection-molded. The machine is screwed and is a small hole.
Die casting machine types are defined with following: Die casting machine type 1: hot chamber die casting machine The hot chamber die casting machine has simple structure, convenient operation and easy realization of automatic production... ....
According to statistics, during the “Eleventh Five-Year Plan” period, foundry enterprises applied for and obtained more than 4,000 patents, including 2,000 invention patents. This shows that Chinese foundry companies have achieved important breakthroughs in the development of efficient and clean energy equipment, as well as high-end castings for the shipbuilding, metallurgy, rail transit, aviation and other industries, and the technological level has been greatly improved.
The cold chamber die casting machine is a die casting machine in which the injection chamber and the injection punch are not immersed in the molten metal, and the quantitative molten metal is poured into the injection chamber and then injected.
Die-casting hot molding machine is also called die-casting mold temperature machine. The automatic control of mold temperature by die-casting hot molding machine is an indispensable means in modern die-casting technology. What is the role of die casting hot molding machine in die casting mold temperature control?
The existence of pressure is the main feature of the die casting process that distinguishes other casting methods. The injection force is the force that pushes the injection piston in [...]
Die casting machines are generally divided into two categories: hot press chamber die casting machine and cold pressure chamber die casting machine. The cold press chamber die casting machine is [...]
Aluminum die casting parts are produced by aluminum alloy, which are good for many applications. Due to the character of aluminum alloy materials, they will not be rusted and can be used for a long time. Usually, what should you pay attention to when storing aluminum alloy die castings?
